1. the volume of a metal object is found to be 45 cm³. its mass is 449 grams. what is the density of this substance?

you must show your work here!

Explanation:

Step1: Recall density formula

The formula for density $
ho$ is $
ho=\frac{m}{V}$, where $m$ is mass and $V$ is volume.

Step2: Substitute given values

Given $m = 449$ g and $V=45$ cm³. So, $
ho=\frac{449\text{ g}}{45\text{ cm}^3}$.

Step3: Calculate density

$
ho=\frac{449}{45}\text{ g/cm}^3\approx9.98\text{ g/cm}^3$.

Answer:

$9.98$ g/cm³
